Abstract
An interactive projection system for displaying an image on a planar surface includes a base, a projector, a convex mirror, and at least one support. The base is disposed on the planer surface. The projector is housed in the base. The projector has an image projecting portion that projects an image along a projection path away from the projector. The at least one support is connected to the base and supports the convex mirror at a position along the projection path so as to face the image projecting portion of the projector and the planar surface.

An interactive projection system for displaying an image on a planar surface, the system comprising:
- a projector housed in a base, the projector having an image projecting portion that projects an image along a projection path away from the projector;
- a convex mirror;
- at least one support connected to the base and supporting the convex mirror at a position along the projection path so as to face the image projecting portion;
- a position indicator for indicating a position on the planar surface;
- a camera mounted on the base and having an image-pick-up portion facing the convex mirror, the camera detecting the position indicated by the position indicator as reflected from the convex mirror;
- and
- a processor for determining positional relationship of the position indicated by the position indicator and the displayed image on the planar surface, and controlling the projector to include a cursor in the image at the position indicated by the position indicator.

An interactive projection system for displaying an image, the system comprising:
- a base disposed on the planar surface;
- a projector housed in the base, the projector having an image projecting portion that projects an image along a projection path away from the projector;
- a convex mirror shaped in a full circle with a center hole as viewed from the image projection portion;
- and at least one support connected to the base and supporting the convex mirror at a position along the projection path so as to face the image projecting portion of the planar surface;
- a position indicator for indicating a position of the image projecting portion of the planar surface;
- a camera mounted on the base and having an image-pick-up portion facing the convex mirror, the camera detecting the position indicated by the position indicator as reflected from the convex mirror;
- and
- a processor for determining positional relationship of the position indicated by the position indicator and the displayed image on the planar surface, and controlling the projector to include a cursor in the image at the position indicated by the position indicator;
- wherein said the displayed image appears in a circular torus shape of the image projection of the planar surface.
